Abstract: A dental vacuum system for use in dental operatories wherein a dental aspirator tip and in the dental operatory is in fluid communication with a vacuum means for providing suction to the system, there being interposed between the aspirator tip and the vacuum means a separation chamber for the separation of effluent, and solids, including amalgam and other particulate matter from the air stream, the separation chamber being in communication with a collection chamber for the separation collection of solids, amalgam and other particulate matter, from the effluent which is discharged, the collection chamber being removably replaceable from the system for the recycling of the contents.

Abstract: There is disclosed a photo-stimulable imaging film restoration apparatus comprised of a housing defining a chamber for a light source and having an opening for a translucent plate member having a front surface including a member for positioning proximate the plate member imaging film for restoration and facile removal by grasping side portions of an imaging film.

Abstract: An imaging plate guide formed in different configurations corresponding to the various intraoral dental plate sizes, which in turn correspond to the dental intraoral film sizes commonly referred to as sizes 0 through 4, the imaging plate guides dedicated to intraoral imaging providing for guides for each plate size so that a desired array of feed width guides can be positioned on the scanner for scanning the intraoral plates and which scan extraoral imaging plates as well. The embodiment of the imaging plate guides provides not only for interchangeability with respect to the intraoral plate size, but also allows for the feeding of extraoral imaging plates without the need to remove the intraoral plate guides. The size 4 is not specifically described, but is analogous to the other sizes as would be obvious to one skilled in the art.

Abstract: A dental vacuum system for use in dental operatories in which a dental aspirator tip in the dental operatory is in fluid communication with a two stage side channel blower for providing suction to the system, there being interposed between the dental aspirator tip and the two stage side channel blower, a solid debris collector and separation chamber for the passage of air and collection of effluent and debris, the air outlet port in the separation chamber having a float valve sealing means, the float valve sealing means having a pivotal lever with a sealing means at one end for engagement with the air outlet port and a float at the opposing lever end for contact with a fluid or foam level within the separation tank, the float depending from the lever end a sufficient distance so as to cause the sealing means to seal the outlet port before any foam can exit the separation tank.

Abstract: There is described a process and apparatus for the physical vapor deposition of an anisotropic phosphor composition with an auto-collimating, optical waveguide structure.

Abstract: An all-terrain riding assembly comprised of a body member, including a supporting surface for feet of the user disposed between a front housing member having a rotatably mounted roller member and a rear housing member having a rotatably mounted, cylindrically-shaped roller member articulatedly mounted to the body member and including an assembly for controlling the rotational velocity of the rear roller member and thus linear velocity of the riding assembly.

Abstract: A photo-curing light system in which a modulation of the light intensity or output is controlled via an analogue control voltage to the control line output of the lamp power supply. The control signal results in the lamp current being reduced from its maximum value to a lower value on a continuous and repeated basis thereby modulating the light and reducing the heating value to surrounding material such as tooth structure during the curing process.

Abstract: Applicant's invention relates to a photo-curing light assembly having calibration circuitry determinative of the intensity level of the light source and the generation of an analogue control voltage from a digital control voltage during use which automatically adjusts light intensity to achieve proper energy levels during programmed curing times.

Abstract: A metal stent for vascular implantation comprising a generally tubular structure whose external surface is adapted to engage the interior vascular surface when implanted, said metal of said stent containing a substantially uniform dispersion of from about 0.05 to about 10.00 percent by weight of one or more naturally occurring or enriched stable isotopes having a half-life of less than two months and that are principally beta particle emitters, so that when activated, said stent emits low to moderate dosages of radiation uniformly to reduce cell proliferation.

Abstract: In a method of producing marking or the like on a surface by means of laser radiation, at least two layers of lacquer of different colors are successively applied to the surface and at least the outer layer which is towards the viewer of the surface is removed by laser radiation in a region-wise manner to expose the second layer therebeneath, thereby producing the marking on the surface. At least the outer layer is applied by a transfer operation from a carrier material, in order thereby to produce a uniform thickness for that layer and thus a highly uniform laser-engraving effect. Also described is the use of embossing foils and more especially hot embossing foils of a particular configuration in such a method.

Abstract: An improved method for the manufacture of a compact brush guide holder assembly which is commonly found on machines in which electricity is to be transferred between an electrically conductive brush element as it moves and makes contact with a rotatable conductor such as a commutator.
